A carbon-fibre is a polymer-fibre that gets heated heavily until its completely charred (carbonation).

Polymers consist of molecules, in which one kind (or different kinds) of atoms or grouped atoms are connected repeatedly. Synthetic polymers, consisting of monomers, are differentiated by their attributes: thermoplastic, duroplastic and elastomers.

Carbon-fibres are created through converting acrylic fibres into graphite fibres.
